// A CommandStream is a bidirectional ACE_Stream implementing a chain
// of commands. A message will move down the stream until a
// CommandModule is capable of processing it. After processing, it
// will move on down the stream to the end. Data received from the
// tail will likewise move up the stream until the downstream's
// partner module is encoutered. The retrieved data will be processed
// and continue on up the stream.
